FOUNTAIN PEN ATTACHMENT Filed July 25, 1933 W41. TE-R G. JTOCKMHN INVENTOR ATTORN EY Patented ay 1, 1934 QFFlCE 2 (llaims.

This invention relates to fountain pen attachments and more particularly to inking stamp attachments for fountain pens.

An object of the invention is the provision of an inking stamp attachment secured to the cap of a fountain pen in combination with means for locking the attachment to the cap when the cap is placed on the barrel, said means also functioning to more securely hold the cap to the barrel.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with th accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such 20 changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. l is a plan view of a fountain pen embodying my attachment.

Fig. 2 is an enlarged view showing the cap in section, as taken approximately on the line 2-2 of Fig. l, and showing fragmentarily the barrel and nib of the pin in plan view.

Figs. 3 and 4 are sections taken on lines 33 and 44 of Fig. 2.

Referring to the drawing for a more detailed description thereof, the numeral '7 indicates a fountain pen barrel carrying a nib 8. A cap 9 of the fountain pen is screw-threaded to the barrel, as shown in Fig. 1, and comprises a body portion 10 having an aperture which receives an ink stamp 11, the print of which is in contact with an inking pad 12.. Said inking pad is secured to a cylindrical tube 13, as by gluing, for example. The tube 13 is attached at its outer end to a knurled turnable end portion 14 which, upon being turned, presents a new contact area of the inking pad to the ink stamp 11. The inking stamp is provided at its ends with outwardly extending tongues 15, one of which extends under an undercut portion 16 of the cap 10, while the other extends under a slidable latch 17 which is held to the cap by means of a U-shaped member 18. A helical spring 20 is held between an inwardly extending portion 17a of the latch 17 and the outer end of the U-shaped holding member 18, said coil also lying between the bottom of the U-shaped member and the horizontal portion of the latch 17.

When the cap is screwed on to the barrel the inwardly extending portion 17a of the latch 17 comes up against a shoulder 7a of the barrel 7 so that the latch moves outwardly into the space 22 between the inner tongue 15 and the upper portion of the inking stamp to lock the latter to the cap. It will be readily appreciated that the pressure of the member 170, against the shoulder 7a of the barrel as caused by the spring 20, will tend to hold the cap to the barrel, or, in other words, tend to prevent the cap from accidentally becoming unscrewed from the barrel. The stamp is provided with a handle 23 pivoted at 24 so that normally'it lies flush with the outer surface of the inking stamp but may be pulled out to facilitate removal of the inking stamp when the latter is to be used.

What is claimed is:

1. A fountain pen comprising a barrel and a nib attached thereto, a cap on the nib end of said barrel, said cap having an elongate aperture in its side wall, a round tubular ink pad within said cap and turnable therein to present diiTerent portions thereof opposite said aperture, stamp means in said aperture and held to said cap and means locking said stamp means to said cap and tending to hold said cap to said barrel.

2. The combination with an apertured cylinder, of an inking pad axially turnable therein, a printing stamp in the aperture of said cylinder and adapted to contact said pad and means detachably connecting said stamp to said cylinder.
